#  Computer Chat Simulator
#
#  Write a program that simulates a chat with your computer.
#  For each input the user makes, the computer should respond
#  with something appropriate or simply say "I don't understand.
#  Please rephrase."  
#
#  You may use your own creativity to decide what the computer
#  says.  When complete, you should be able to type "quit" and the 
#  program should exit.
#
#  Note:  For the purpose of this exercise, your program only
#   needs to have 5-6 things that the computer responds to
#
#  Example:
#
#	Welcome to CompuChat!
#	you>Hello
#	computer>Hello to you
#	you>what's your favourite colour?
#	computer>blue, thanks for asking
